Jenner, shockingly, thinks the outfit is a great idea. But had a surprising criticism for the makers.

"I could have done my own costume! I mean, that was a serious bustier on the cover of Vanity Fair. I mean at least get some good clothes," she said. "You've got to enjoy life. Life's too short. I can't get too upset about that type of stuff."

Jenner also revealed that she doesn't get upset about the pronoun usage when Lauer explained that he was nervous for their interview because he didn't want to offend anyone.

"And to be honest with you, I'm the easiest on people. Now the community, you know, GLAAD, all the people in the community, are like, 'Oh, my god, you have to get the pronouns right. You have to do this, you have to do that.' I'm much more tolerant than that. I mean, I understand that, you know, it's difficult for people to understand this, and that's OK."

But Jenner said she's more than happy with her decision.

"I think about my life — and where I'm at in my life right now. What a tremendous experience this is," she said. "Hardly nobody gets to live two genders in their life."
